We are surrounded by things that we do not know. We are surrounded by terra incognitae. Too often someone believes to know everything about someone or something – only to find out one day that this has been an illusion. To find answers may be a life-long mission impossible. Whenever a researcher or thinker believes to have found an answer, exactly this answer is giving birth to new questions he was not been aware of before. So there won´t be an end to this search, probably not even in death. We do not know anything about the future. But what do we really know about present and past? We do not know the others, and we do not know ourselves too. And each of us is a terra incognita too. What do we know about death? Nothing. Death is another terra incognita. What do we know about life and love? We are everywhere surrounded by unknown territories. Some are trying to find answers for this mission impossible in philosophy or religion, and a part of them might be successful but actually most of those searching probably will never find an answer. Children are full of questions: Why is the sky blue? Why is so much salt in the sea? I love these questions. Maybe they are more important than the answers.​
